A new red band trailer for Seven Psychopaths (featuring Colin Farrell) teases the dark comedy's obscenity-laced dialogue - courtesy of Oscar-winning filmmaker Martin McDonagh - as well as the deranged weirdos brought to life by actual odd "characters" like Christopher Walken, Woody Harrelson, and Tom Waits.

Most of the footage here couldn't make into the green band trailer for reasons of language; specifically, an abundance of f-bombs mixed with subversive humor along the lines of McDonagh's In Bruges (also starring Farrell). Here, the filmmaker trades in the bleak hues of Belgium for warmer San Fernando Valley, while keeping the mood a bit lighter - but with characters as quirky as In Bruges' players.

Previous marketing for Seven Psychopaths focused on Colin Farrell as a struggling screenwriter who begins to incorporate the animated personalities around him into his work. That includes dog-napping buddies Sam Rockwell and Christopher Walken (though, Rockwell prefers the term dog-borrowing), as well as Farrell's impatient girlfriend Abbie Cornish - not to mention, an old man who never lets go of his pet white rabbit (Waits).

The red band promo offers a better look at the side players, especially Woody Harrelson as the gangster who comes looking for blood after Rockwell and Walken kidnap his beloved Shih Tzu by accident. Harrelson's role was originally going to be occupied by Mickey Rourke - who, as it were, is a real-life bruiser known for being very affectionate towards his pet chihuahuas.

It seems as though the gangster character in Seven Psychopaths was based on Rourke to some degree - especially when you consider how Harrelson shifts from a murderous rage in one scene to cringing and whimpering on the ground (pleading to just scratch his hostage pet a couple times) in the next.

Seven Psychopaths is more than a twisted tale of writers, thieves, and dangerous criminals; it also mirrors McDonagh's experiences as a storyteller, constantly on the search for inspiration from the world around him - quite literally, as Farrell plays a character named Martin, who is writing a script titled... Seven Psychopaths. The rest of the film isn't quite so literal, though (one hopes - ?).

Fans of In Bruges tend to highlight McDonagh's witty wordplay - not to mention, his ability to shift from stark drama to bizarre comedy at the turn of a dime. Seven Psychopaths appears to maintain a more consistent tone than In Bruges, but it has the makings of an equally-memorable (and unusual) time at the movies.

Look for Seven Psychopaths to hits U.S. theaters on October 12th, 2012.
